L. R. Taft had excellenl results in recenl experiments with proprietary soluble 

 petroleum compounds, butstill prefers lime-sulphur wash. In Illinois the soluble 

 ( ,il compounds proved to he equally effective with lime and sulphur, hut somewhal 

 more expensive. It was found undesirable, however, to use the lime and sulphui 

 during midwinter. Apparently better resultsare obtained when these compounds 

 are used in the spring or fall. In recent experiments by numerous inspectors Con- 

 Sol proved to be practically useless. The kerosene-limoid mixture in recenl tests in 

 Ohio and Delaware also gave poor results. 



The association also discussed the points which should be covered by an inspec 



tion certificate. In this discussion it appeared that in New Jersey and some other 



states a certificate is given subjed to the right to a second inspection before the I 

 are removed from the nursery rows. An inspection in July without reinspection is 

 considered of no value. In Ohio the requirements of the law make it necessary 

 to inspect nurseries rather earl) in the season. The point was emphasized, however, 



by all who took pari in tin- discus-ion that nurseries should he inspected as late in 



the season as possible. 



[n order to secure uniformity of certificates and inspection it was recommended 

 that a standard list of dangerous pests he prepared. Asa result of this discussion a 

 committee was appointed to draw up such a list, and this committee was later c( n- 

 tinued in order to enable it to complete its work. 



Nearly all of the inspectors had experienced great difficulty in drawing a sharp 

 line between nurserymen and dealers. It was recognized that there are certain 

 dealers who virtually raise no nursery stock of their own. On the other hand, all 

 nurserymen trade stock with one another and buyandsell. In some cases even the 

 largest nurserymen buy more stock than they raise on their own premises. This 

 fact hrin^s into prominence the difficulty of issuing certificates which shall cover the 

 nursery stock raised on the premises inspected, and also other stock bought in other 

 state- with another inspector's certificate, hut not inspected by the local inspector. 



After discussing this matter a resolution was passed to the effect thai a nursery 



in the inspectors' sense is any place where hardy fruit or ornamental trees, vines, 



shrubs, and plants are grown for sale or distribution. 



The inspectors took up the discussion of the attitude of commercial fruit growers 

 toward the inspection vvork for the control of San Jose scale. In general the reports 

 of different inspectors on this point indicated clearly a growing feeling among the 

 orchardists and commercial fruit growers of the importance of inspection by compe- 

 tent inspectors and thorough application of standard insecticides. 



In Maryland and New York orchard.- are inspected as far as the fund- of the 

 inspection Bervice permit. In New Jersey orchardists have the right to requesl 

 inspection. In general, however, it appears that in this State the orchardists are 

 not much concerned about the condition of nursery stock for the reason that they 

 must, in any event, fight the San Jose" scale, and long experience has taught them 

 effective methods for it- conl ml. In Illinois from |6,000 to$8,000 are -pent annually 

 on orchard inspection. 



At the surest ion ot II. T. I'ernald, who sent a short paper to he read at the 

 meeting, the inspection for gypsy moth and brown-tail moth was discussed. Atten- 

 tion was called to the great difficulty of inspecting nurseries for these pests. The 

 requirements of the Massachusetts law make it necessary t<> inspect nursery stock at 

 a season before the eggs of the gypsy moth are laid. It appears quite possible that
